*Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Absolute maximum  ratings apply individually only, not in combination. Unless otherwise specified, all voltages are referenced to PGND.


Description

The ADP3418 is a dual high voltage MOSFET driver optimized for driving two N-channel MOSFETs, which are the two switches in a nonisolated synchronous buck power converter. Each of the drivers is capable of driving a 3000 pF load with a 20 ns propagation delay and a 30 ns transition time. One of the drivers can e bootstrapped and is designed to handle the high voltage slew rate associated with floating high-side gate drivers. The ADP3418 includes overlapping drive protection to prevent shoot-through current in the external MOSFETs. The OD pin shuts off both the high-side and the low-side MOSFETs to prevent rapid output capacitor discharge during system shutdown.

The ADP3418 is specified over the commercial temperature range of 0°C to 85°C and is available in a thermally enhanced 8-lead SOIC package.
